The NGT is intended for gastric decompression, gastric suction, administration of nutritional supplements and medication, and to monitor core temperature.
The NGT Nasogastric Tube is made of a plastic material, contains three lumens, a main suction lumen, a smaller vent lumen, and a still smaller temperature thermistor lumen. The primary suction lumen is used for drainage, the second vent lumen provides an air inlet as a mechanism to break suction minimizing the potential for tube blockage secondary to mucosal tissue invagination into the side holes of the primary lumen. The device is intended to be used with a standard suction source to facilitate drainage.
The provided 510(k) summary for K022558 focuses on demonstrating substantial equivalence of the NGT Nasogastric Thermistor device to predicate devices. It states that "Bench testing was performed on the NGT to demonstrate equivalency." However, the summary does not provide any specific acceptance criteria or detailed results of this performance testing.
Therefore, I cannot populate the table or answer most of the questions as the required information is not available in the given text.
Here's a breakdown of what can be extracted and what cannot:
1. Table of Acceptance Criteria and Reported Device Performance:
| Acceptance Criteria | Reported Device Performance |
|---|---|
| NOT PROVIDED | NOT PROVIDED |
| No specific performance metrics, thresholds, or results are mentioned in the document. | The document only states "Bench testing was performed... to demonstrate equivalency," without detailing what equivalency entailed in terms of specific performance measures. |
2. Sample size used for the test set and the data provenance:
- Sample size: Not provided.
- Data provenance: Not provided (the document only mentions "Bench testing," which implies laboratory-based testing, but no details on data origin or type are given).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. This device is a medical tube with a temperature sensor, not an AI/Software as a Medical Device (SaMD) requiring expert-established ground truth for interpretation of images or other complex data. The document describes bench testing for equivalency, not a study involving expert review of results.
4. Adjudication method for the test set:
- Not applicable. (See answer to #3)
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- Not applicable. This is not an AI/SaMD device.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
- Not applicable. This is a physical medical device, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- Not applicable in the conventional sense for a physical device. For "bench testing," ground truth would typically refer to known physical properties, measurements from calibrated reference instruments, or specified performance standards for gastric suction and temperature sensing. The document does not specify these.
8. The sample size for the training set:
- Not applicable. This is a physical medical device, not an machine learning model requiring a training set.
9. How the ground truth for the training set was established:
- Not applicable. (See answer to #8)

- Device Name Proprietary Name: NGT Nasogastric Thermistor Common/Usual Name: Nasogastric Tube
-
- Identification of Predicate or Legally Marketed Device
- Device Description 4.
The NGT Nasogastric Tube is made of a plastic material, contains three lumens, a main suction lumen, a smaller vent lumen, and a still smaller temperature thermistor lumen. The primary suction lumen is used for drainage, the second vent lumen provides an air inlet as a mechanism to break suction minimizing the potential for tube blockage secondary to mucosal tissue invagination into the side holes of the primary lumen. The device is intended to be used with a standard suction source to facilitate drainage.
-
- Intended Use
The NGT is intended for gastric decompression, gastric suction, administration of nutritional supplements and medication, and to monitor core temperature.
- Intended Use
-
- Comparison of Technological Characteristics
The NGT Nasogastric Tube has similar technological characteristics to the Bard Nasoqastric Sump Tube and the Argyle Salem Sump Tube in that the materials are the sizes available are within the range of sizes currently available, but the NGT Nasogastric Tube incorporates a temperature monitoring capability. This temperature monitoring capability is similar to the Mallinckrodt Mon-a-therm Esophageal Stethoscope with temperature sensor. However, the NGT Nasogastric Tube incorporates this temperature thermistor into a third lumen whereas the other predicates all have 2 lumens.
- Comparison of Technological Characteristics
The differences in the configurations of each of the devices do not affect the ability of the device to suction gastric fluids. Each of the devices requires monitoring by the clinical staff to assure proper nasogastric tube function. Each of the devices uses the same operating principal.
7 Performance Testing
Bench testing was performed on the NGT to demonstrate equivalency.

Dear Ms. Iampietro:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
